One of the reactions that occurs in a blast furnace, where iron ore is converted to cast iron, is: Fe2O3 + 3CO?

one of the reactions that occurs in a blast furnace, where iron ore is converted to cast iron, is: Fe2O3 + 3CO gt; 2Fe + CO2 Suppose that 1.64 x 10^3 kg of Fe are obtained from a 2.62 x 10^3 kg sample of Fe2O3. Assuming that the reaction goes to completion, what is the percent purity of Fe2O3 in the original sample?Please help!! This is the last question I need to finish from my whole summer assignment for AP Chem, but I have no idea how to do it! Help!
